PURPOSE: A fan-motor driver which is installed in a plasma displaying device is provided to control the fan-motor in a real time and prevent the unneeded driving of the fan-motor. CONSTITUTION: A fan-motor driver drives a fan-motor by applying a DC current between the anode terminal and the cathode terminal of the fan-motor which discharges the heat which is generated in a plasma display device. An anode terminal of a DC power source is connected to the anode terminal of the fan-motor, and a cathode terminal of the DC power source is connected to the ground terminal. A collector of a driving transistor is connected to a cathode terminal of the fan-motor, and the emitter of the driving transistor is connected to the ground terminal. The fan-motor driver comprises the DC power source, the driving transistor, and a thermistor.
